The Helian economic system is currently under development. However, our currency is now official. The Sol is equal to US$10. A Decisol=US$1, a Centisol=US$0.10, a Millisol=US$0.01. As you can see, it is based on the metric system. As such, a Dekasol=US$100, a Hectasol=US$1000, and a Kilosol=US$10,000.
